About this work
Located in the constellation Hercules about 22,200 light-years from Earth, M13 (or the Great Globular Cluster in Hercules) packs several hundred thousand ancient stars into a diameter of roughly 145 light-years. Within the same field of view, one can observe NGC 6207, a beautiful spiral galaxy located much farther away, about 46 million light-years distant. By carefully examining the space between the cluster and this galaxy, one can also distinguish IC 4617, a tiny spiral galaxy lost in the depths of the distant universe, over 500 million light-years away. The bright orange star in the middle is TYC2588-2833-1, and the bright white star in the right is HD 150679.
